As spiritual beings in physical form, the idea of reincarnation just makes sense unless one doesn't believe we are spiritual beings.

in any case we are all entitled to our opinions and experiences regarding this.

I believe in reincarnation 100% but also understand some memories/knowledge is genetic and ancestral.

DNA is very powerful stuff.

Another thought to ponder is the physical form is often a reflection from the previous life and certain birth defects or birth marks may be the result from past life trauma. for instance, a person with a birth mark on their temple may have been shot in the head in another life. DNA remembers and manifests the scar in this incarnation.

Dr. Ian Stevenson of the University of Virginia has done extensive research on reincarnation and how our current bodies reflect our past life's experiences.

Also, since we do live in a linear world timeline, the concept of simultaneous existences co-existing is hard for most people to grasp. exploring the concepts of reincarnation is a great way to start exploring our unseen universe.
